STORE-VAT.

Specification of Letters Patent.

Patented July 4, 1911.

Application filed October 1 1, 1910. Serial No. 586,448.

To all whom it may concern:

Be it known that I, WILHELM SoHMrrr, a subject of the German Emperor,and resident of No. 1 Loherstrasse, Schwelm, Westphalia, in the Empireof Germany, engineer, have invented new and useful Improvements inStore-vats, of which the following is a specification.

It is already known to make metal storevats of the size necessary forbrewery installations by assembling separate rings or flanged sockets soas to form one single self-contained chamber, whose flanges are packedby interposed packing material. The vats made in this manner havehowever the drawback that owing to the packing joints of the flanges,the contents of the vat come in contact with the packing materialand'numerous joints are also formed which assists the formation andaccumulation of numerous bacteria. This drawback is obviated by thepresent invention by making the vat of several elements or cells, eachforming a receptacle closed on all sides and having a smooth inner.surface. The said cells are disposed one over the other and side by sidein the form of columns and are assembled or combined with abutting andrelatively supported heads or bottoms, the inner spaces of the cellscommunicating with each other through the medium of externally providedfittings. A combined receptacle divided by intermediate walls orpartitions is thus formed which is nevertheless adapted to be filled asa whole and has the advantages of the jointless vat. This combinedreceptacle also possesses the advantage that it permits a partialemptying of its system of cells at any part thereof. Owing to the singlereceptacles bein connected at their heads or bottoms, the atter may bemade weaker than the side walls; consequently, in order that theuniformly shaped receptacles may be readily replaced at any part of thecolumns of the cells, they are of a comparatively light weight,especially as they have small dimensions so as to allow of their beinginserted in spaces or chambers provided with small doors or the like.The head or bottom, which is convex toward the interior of each cell orelement of the vat permits an accumulation of slimy or yeasty separatedmatter in a groove-like depression extending along the inner peripheryof the cell and from which the impurities may be easily removed.Finally, owing to the novel construction of the vat, the effect oradvantage is attained that it may considerably exceed the height of 3meters, which had heretofore to be maintained, because a higher liquidcolumn produced many variations in the beer when standing. This drawbackis obviated by the vat according to this invention in that it ispractically divided into sections or compartments whereby aninterruption of the liquid-column is effected.

The accompanying drawing shows a store vat constructed according to thisinvention.

Figure 1 is a side-elevation with partial section of the store-vatdisposed vertically and Fig. 2 is a side-elevation of the store vatdisposed horizontally.

The vat comprises several superposed cells or chambers a, of which thereare three in the construction as shown in Fig. 1 of the drawing, eachforming a receptacle closed on all sides; these chambers are made of asingle welded piece of suitably rolled wrought iron and preferablyenameled inside, so that they have a perfectly smooth inner surface. Thecolumn-like-super-position of these elements of the vat is effected insuch a manner that one element of the vat is placed with its lowerconcave bottom-surface on the convex outer-surface of the upper bottomof the lowermost body of the vat and so on. The annular intermediatespaces 6 on the periphery of the joints of two superposed elements ofthe vat are preferably filled with cement or any other suitablematerial, which assists in preventing a displacement of the individualreceptacles and also gives the combined body a uniform appearance.

The relative intercommunication of the various receptacles a is effectedby the externally provided flanged socket fittings 0 wherein the threeway cocks (Z or the like and the rubber tube screwing rings e can besimultaneously interposed and also the ventilating pipes 7 provided withvalves can be inserted. The valves (Z may be constructed as three waycocks or in any other suitable manner in order, if necessary, toseparately tap the cells at any part of the column.

A pipe 9 adapted for cleaning purposes and provided externally with acock communicates with the groove-shaped depression formed inconsequence of the concavity of the lowermost bottom of the cell, suchbottom being connected to the convex upper bottom of the lowermost cell.

Fig. 2 shows a vat, which, in accordance with this invention, alsocomprises several cells or chambers disposed according to the columnsystem; these cells or chambers are however not arranged one over theother but side by side with their heads or bottoms abutting against eachother. It is recommended to embed in masonry m or the like the outerbottoms or heads of the vat, which may both have an outwardly bulgedshape in order to resist the pressure exerted in an axial direction ofthe vat.

Z indicates the manholes provided in the various cells of the vat.

In the vertical arrangement as Well as in the horizontal arrangement,either one or the other of the two bottoms of each receptacle or cell,or both of them, may have a less wall-thickness than the side-walls ofthe said receptacle or cell, because two abutting bottoms alwayscomplete the necessary intermediate wall-thickness. Thus a certainsaving of material is effected which must be Copies of this patent maybe obtained for five cents each, by addressing the Commissioner ofPatents,

taken into consideration for the purpose of easily hand ing the separatecells of the vat when transporting and mounting them. Moreover, thecells 01 elements of the vat are preferably of the same shape so thatthey so can be readily arranged or replaced at any part of thecolumn-system. V

HZLViIlg now particularly described and ascertained the nature of mysaid invention and in what manner the same is to be performed, I declarethat what I claim and wish to secure by Letters Patent is In a storevat, the combination of a plurality of juxtaposed individual cells, eachof which comprises a body portion having in- 4 tegrally formedimperforate concave and convex heads, respectively, of less thicknessthan the body portion thereof, the convex head of one cell fitting intothe concave head of an adjacent cell, and means whereby the said cellsmay be filled and emptied.
